Taschenbuch. Condizione: Neu. Neuware -¿ What is Exploring Abstract Algebra with Mathematica Exploring Abstract Algebra with Mathematica is a learning environment for introductory abstract algebra built around a suite of Mathematica packages enti tled AbstractAlgebra. These packages are a foundation for this collection of twenty-seven interactive labs on group and ring theory. The lab portion of this book reflects the contents of the Mathematica-based electronic not Elektronisches Buch con tained in the accompanying CD-ROM. Students can interact with both the printed and electronic versions of the material in the laboratory and look up details and reference information in the User's Guide. Exercises occur in the stream of the text of labs, providing a context in which to answer. The not Elektronisches Buch are designed so that the answers to the questions can either be entered into the electronic notebook or written on paper, whichever the instructor prefers. The not Elektronisches Buch support versions 2. 2 and 3. 0-4. 0 and are compatible with all platforms that run Mathematica. This work can be used to supplement any introductory abstract algebra text and is not dependent on any particular text. The group and ring labs have been cross referenced against some of the more popular texts. This information can be found on our web site at www . central. edu/eaarn. htrnl (which is also mirrored at www . urnl. edu/Dept/Math/eaarn/eaarn. htrnl). If your favorite text isn't on our list, it can be added upon request by contacting either author.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 484 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Facing the Consequences presents a perspective on US mathematics and science education that is developed from data gathered as part of the Third International Mathematics and Science Study (TIMSS). TIMSS is the most extensive and far-reaching cross-national comparative study of mathematics and science education ever attempted. It includes comparing official curricula, textbooks, teacher practices, and student achievements for many countries (from 20 to 50 countries, depending on the particular comparison). Thousands of official documents and textbooks were analyzed. Thousands of teachers, principals, and other experts responded to survey questionnaires. A sample of mathematics teachers in three countries had their lessons videotaped. Hundreds of thousands of children in almost 50 countries were tested in mathematics and science.This report presents a closer look at US mathematics and science education through careful examination of TIMSS data. The authors believe this investigation shows how deceptive many often unquestioned assumptions about American education can be. Drawing upon many new analyses not previously reported and integrating these with previous analyses of TIMSS data, the authors develop and illustrate the argument that what happens to American students is the consequence of American beliefs that shape educational practice and the accretion of a myriad educational choices made in mathematics and science education. 248 pp. Englisch.

Buch. Condizione: Neu. Neuware -In America and Europe, carbon dioxide has been widely used as the distention medium in hysteroscopy, in contrast to the widespread use of liquid hysteroscopy in Japan. There are merits and demerits for both media, but the author prefers liquid hysteroscopy because of reduced leakage into the abdominal cavity, reduced glare, and improved debris removal. Although TV images captured with a flexible endoscope are employed for routine work, the author insists on using a single-lens reflex camera with a rigid endoscope for producing wonderfully clear photographs. Having carried out between 400 and 550 examinations a year for the last 20 years, the author has built up an impressive library of quintessential diagnostic images. Over 200 of these photographs are reproduced in color in this atlas to provide a visual guide to uterine abnormalities of unparalleled breadth and clarity.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 188 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Variations in seismic Q are sensitive to a much greater extent than are seismic velocity variations on factors such as temperature, fluid content, and the movement of solid state defects in the earth. For that reason an understanding of Q and its variation with position in the earth and with time should provide information in earth's tectonic evolution, as well as on aspects of its internal structure. Progress in understanding Q has suffered from difficulty in obtaining reliable amplitude data at global and temporary stations. Moreover, laboratory determinations of Q, until recently, were most often made at frequencies much higher than those measured by seismologists for waves propagating through the earth. Recent advances in seismic station distribution and quality, as well as in methodology at both high and low fequencies, have greatly improved the quality of observational data available to seismologists from global stations. Concurrent advances have been made in measuring Q using laboratory samples at frequencies that pertain to the earth and in theoretical understanding of seismic wave attenuation. Papers of this volume present new information on Q in the earth from several perspectives: methodology, results from global and regional observations of both body and surface waves, laboratory measurements, and theoretical understanding. The editors believe that we have reached a new threshold in Q studies and that advances in data quality and methodology will spur increased interest in this difficult, but interesting field. 508 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Local-regional anesthesia and pain therapy represent two areas of common interest for all physicians. A thorough preparation in functional anatomy and general pharmacology, including familiarity with local anesthetics and analgesics, is considered fundamental background for further study or clinical application of such techniques. Knowledge of the mechanisms of action, efficacies and side effects of the relevant drugs is essential, as is appreciation of possible drug interactions to evaluate eventual toxic effects. Local-regional anesthesia and pain management are being increasing used in diverse medical specialties, including those requiring manual dexterity. In contemporary medicine correct evaluation of the medical outcome becomes essential, especially in relation to the cost-benefit balance, not only in terms of the resources consumed, also and more importantly for the quality of life of the patient.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 364 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Genetic Algorithms (GA) as a tool for a search and optimizing methodology has now reached a mature stage. It has found many useful applications in both the scientific and engineering arenas. The main reason for this success is undoubtedly due to the advances that have been made in solid-state microelectronics fabrication that have, in turn, led to the proliferation of widely available, low cost, and speedy computers. The GA works on the Darwinian principle of natural selection for which the noted English philosopher, Herbert Spencer coined the phrase 'Survival of the fittest'. As a numerical optimizer, the solutions obtained by the GA are not mathematically oriented. Instead, GA possesses an intrinsic flexibility and the freedom to choose desirable optima according to design specifications. Whether the criteria of concern be nonlinear, constrained, discrete, multimodal, or NP hard, the GA is entirely equal to the challenge. In fact, because of the uniqueness of the evolutionary process and the gene structure of a chromosome, the GA processing mechanism can take the form ofparallelism and multiobjective. These provide an extra dimension for solutions where other techniques may have failed completely. It is, therefore, the aim ofthis booktogather together relevant GA materialthat has already been used and demonstrated in various engineering disciplines.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 360 pp. Englisch.

Buch. Condizione: Neu. Neuware -Arithmetic geometry and algebraic dynamical systems are flourishing areas of mathematics. Both subjects have highly technical aspects, yet both of fer a rich supply of down-to-earth examples. Both have much to gain from each other in techniques and, more importantly, as a means for posing (and sometimes solving) outstanding problems. It is unlikely that new graduate students will have the time or the energy to master both. This book is in tended as a starting point for either topic, but is in content no more than an invitation. We hope to show that a rich common vein of ideas permeates both areas, and hope that further exploration of this commonality will result. Central to both topics is a notion of complexity. In arithmetic geome try 'height' measures arithmetical complexity of points on varieties, while in dynamical systems 'entropy' measures the orbit complexity of maps. The con nections between these two notions in explicit examples lie at the heart of the book. The fundamental objects which appear in both settings are polynomi als, so we are concerned principally with heights of polynomials. By working with polynomials rather than algebraic numbers we avoid local heights and p-adic valuations.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 228 pp. Englisch.

Buch. Condizione: Neu. Neuware -Today, our world increasingly is conceived of as being molecular. An ever widening range of phenomena are described logically in terms of molecular properties and molecular interactions. The majority ofknown molecules are heterocyclic and heterocycles dominate the fields ofbiochemistry, medicinal chemistry, dyestuffs, photographic science and are of increasing importance in many others, including polymers, adhesives, and molecular engmeenng. Thus, the importance of heterocyclic chemistry continues to increase and this three volume work by Drs. R. R. Gupta, Mahendra Kumar and Vandana Gupta is a welcome addition to the available guides on the subject. Its scope places it in a useful niche between the single-volume texts and monographs ofheterocyclic chemistry and the multivolume treatises. The authors have retained the well tried classical approach but have succeeded in placing their own individual spin on their arrangement. They have put together a well selected range from among the most important ofthe vast array of facts available. This factual material is ordered in a clear and logical fashion over the three volumes. The present work should be of great value to students and practitioners ofheterocyclic chemistry at all levels from the advanced undergraduate upwards. It will be of particular assistance in presenting a clear and modem view of the subject to those who use heterocycles in a variety of other fields and we wish it well.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 660 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Today, software professionals recognize that change in software systems is inevitable. There are many systems currently in operation, however, which were developed before the need for change was understood. Such systems are commonly referred to as 'legacy systems', and were developed with relatively short lifetimes in mind. Software engineering is a relatively young discipline which is continually improving to provide better support for the development of software systems. What were once state-of-the-art techniques, tools, and processes are now dated, and have resulted in systems which are not responsive to change. For historical reasons, dated development practice traded maintainability for other system attributes, such as cost and performance. A significant number of legacy systems remain in operation because they are critical to the business processes which they support. The combination of extended lifetimes and poor maintainability means that legacy systems are expensive to change, and in many cases they cannot accommodate emerging requirements. This is clearly an undesirable situation, which, until recently, has been tackled by replacing the system or attempting to maintain it. Replacing a legacy system is dangerous, since you face the risk of losing vital business knowledge which is embedded in many old systems. In many cases, system replacement is not cost-effective. Conversely, if you attempt to maintain a legacy system, there is often little return on the investment in maintenance effort and the system remains difficult and expensive to change.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 200 pp. Englisch.

Buch. Condizione: Neu. Neuware -This volume presents detailed discussions of a number of unsolved conceptual and technical issues arising, in particular, in the foundations of quantum theory and the philosophy of science. The 14 contributions capture a wide variety of viewpoints and backgrounds. Some chapters deal primarily with the main experimental issues; others focus on theoretical and philosophical questions.

Buch. Condizione: Neu. Neuware -ItisnowwellknownthatFermat¿slasttheoremhasbeenproved. For more than three and a half centuries, mathematicians ¿ from the greatnamestothecleveramateurs¿triedtoproveFermat¿sfamous statement. The approach was new and involved very sophisticated theories. Finallythelong-soughtproofwasachieved. Thearithmetic theory of elliptic curves, modular forms, Galois representations, and their deformations, developed by many mathematicians, were the tools required to complete the di cult proof. Linked with this great mathematical feat are the names of TANI- YAMA, SHIMURA, FREY, SERRE, RIBET, WILES, TAYLOR. Their contributions, as well as hints of the proof, are discussed in the Epilogue. This book has not been written with the purpose of presentingtheproofofFermat¿stheorem. Onthecontrary, itiswr- ten for amateurs, teachers, and mathematicians curious about the unfolding of the subject. I employ exclusively elementary methods (except in the Epilogue). They have only led to partial solutions but their interest goes beyond Fermat¿s problem. One cannot stop admiring the results obtained with these limited techniques. Nevertheless, I warn that as far as I can see ¿ which in fact is not much ¿ the methods presented here will not lead to a proof of Fermat¿s last theorem for all exponents. vi Preface The presentation is self-contained and details are not spared, so the reading should be smooth. Most of the considerations involve ordinary rational numbers and only occasionally some algebraic (non-rational) numbers. For this reason I excluded Kummer¿s important contributions, which are treated in detail in my book, Classical Theory of Algebraic N- bers and described in my 13 Lectures on Fermat¿s Last Theorem (new printing, containing an Epilogue about recent results).Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 424 pp. Englisch.

Buch. Condizione: Neu. Neuware -The first edition of this book was very well received by the various groups (lecturers, students, researchers and industrialists) interested in the scientific and techno logical aspects of cheese. The initial printing was sold out faster than anticipated and created an opportunity to revise and extend tht; baok. The second edition retains all 21 subjects from the first edition, generally revised by the same authors and in some cases expanded considerably. In addition, 10 new chapters have been added: Cheese: Methods of chemical analysis; Biochemistry of cheese ripening; Water activity and the composition of cheese; Growth and survival of pathogenic and other undesirable microorganisms in cheese; Mem brane processes in cheese technology, in Volume 1 and North-European varieties; Cheeses of the former USSR; Mozzarella and Pizza cheese; Acid-coagulated cheeses and Cheeses from sheep's and goats' milk in Volume 2. These new chapters were included mainly to fill perceived deficiencies in the first edition. The book provides an in-depth coverage of the principal scientific and techno logical aspects of cheese. While it is intended primarily for lecturers, senior students and researchers, production management and quality control personnel should find it to be a very valuable reference book. Although cheese production has become increasingly scientific in recent years, the quality of the final product is still not totally predictable. It is not claimed that this book will provide all the answers for the cheese scientist/technologist but it does provide the most com prehensive compendium of scientific knowledge on cheese available. 592 pp. Englisch.

Buch. Condizione: Neu. Neuware -I am very pleased and privileged to write a short foreword for the monograph of Dean Driebe: Fully Chaotic Maps and Broken Time Symmetry. Despite the technical title this book deals with a problem of fundamental importance. To appreciate its meaning we have to go back to the tragic struggle that was initiated by the work of the great theoretical physicist Ludwig Boltzmann in the second half of the 19th century. Ludwig Boltzmann tried to emulate in physics what Charles Darwin had done in biology and to formulate an evolutionary approach in which past and future would play different roles. Boltzmann's work has lead to innumerable controversies as the laws of classical mechanics (as well as the laws of quan tum mechanics) as traditionally formulated imply symmetry between past and future. As is well known, Albert Einstein often stated that 'Time is an illusion'. Indeed, as long as dynamics is associated with trajectories satisfy ing the equations of classical mechanics, explaining irreversibility in terms of trajectories appears, as Henri Poincare concluded, as a logical error. After a long struggle, Boltzmann acknowledged his defeat and introduced a probabil ity description in which all microscopic states are supposed to have the same a priori probability. Irreversibility would then be due to the imperfection of our observations associated only with the 'macroscopic' state described by temperature, pressure and other similar parameters. Irreversibility then appears devoid of any fundamental significance. However today this position has become untenable.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 176 pp. Englisch.

Buch. Condizione: Neu. Neuware - The title of this proceedings comes from the book The Antibiotic Paradox by Stuart B. Levy (Plenum Publishing Corporation, 1992), referring to the paradox that the more antibiotics are used to treat infectious diseases, the less effective they become. When antibiotics were first introduced, they were considered wonder drugs because they were so effective. But with time bacteria have become resistant to nearly all antibiotics, and resistance is spreading faster than new antibiotics are being developed. This book will identify the issues concerning resistance, as well as describe efforts to develop new drugs that overcome the problem of resistance.

This book provides a survey on line and hyperplane location combining analytical and geometrical methods. The major portion of the text presents new results on this topic, including the extension of some special cases to all distances derived from norms and a discussion of restricted problems in the plane. Almost all results are proven in the text and most of them are illustrated by examples. Furthermore, relations to classical facility location and to problems in computational geometry are pointed out. Audience: The book is suitable for researchers, lecturers, and graduate students working in the fields of location theory or computational geometry.

Buch. Condizione: Neu. Neuware -Summarises the currently available seismic and engineering data pertaining to the seismic hazard of the capitals of the Central Asian republics. The conclusion is that the risk to residents of these cities is extremely high. There is a roughly 40% probability that an earthquake will occur near one of the Central Asian republic's capitals within the next 20 years. Such an event will produce ground shaking in the affected city equal to the maximum ground shaking experienced in Armenia and Sakhalin, i.e. MSK IX. The event will cause tens of thousands of fatalities and at least 100,000 serious injuries.Audience: All people interested in the development of the post-Soviet Central Asian Republics. Earthquake engineers in particular will appreciate the summary of the latest seismic hazard and building vulnerability data of the region; the best compilation of these data available in the English language.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 276 pp. Englisch.

Buch. Condizione: Neu. Neuware -Solidarity as a phenomenon lies like an erratic block in the midst of the moral landscape of our age. Until now, the geologists familiar with this landscape - ethicists and moral theorists - have taken it for granted, have circumnavigated it! in any case, they have been incapable of moving it. In the present volume, scientists from diverse disciplines discuss and examine the concept of solidarity, its history, its scope and its limits.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 364 pp. Englisch.

Buch. Condizione: Neu. Neuware -Decision Criteria and Optimal Inventory Processes provides a theoretical and practical introduction to decision criteria and inventory processes. Inventory theory is presented by focusing on the analysis and processes underlying decision criteria. Included are many state-of-the-art criterion models as background material. These models are extended to the authors' newly developed fuzzy criterion models which constitute a general framework for the study of stochastic inventory models with special focus on the real world inventory theoretic reservoir operations problems. The applications of fuzzy criterion dynamic programming models are illustrated by reservoir operations including the integrated network of reservoir operation and the open inventory network problems.An interesting feature of this book is the special attention it pays to the analysis of some theoretical and applied aspects of fuzzy criteria and dynamic fuzzy criterion models, thus opening up a new way of injecting the much-needed type of non-cost, intuitive, and easy-to-use methods into multi-stage inventory processes. This is accomplished by constructing and optimizing the fuzzy criterion models developed for inventory processes.Practitioners in operations research, management science, and engineering will find numerous new ideas and strategies for modeling real world multi- stage inventory problems, and researchers and applied mathematicians will find this work a stimulating and useful reference.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 228 pp. Englisch.

Buch. Condizione: Neu. Neuware -It is hardly a revelation to note that wireless and mobile communications have grown tremendously during the last few years. This growth has placed stringent requi- ments on channel spacing and, by implication, on the phase noise of oscillators. C- pounding the challenge has been a recent drive toward implementations of transceivers in CMOS, whose inferior 1/f noise performance has usually been thought to disqualify it from use in all but the lowest-performance oscillators. Low noise oscillators are also highly desired in the digital world, of course. The c- tinued drive toward higher clock frequencies translates into a demand for ev- decreasing jitter. Clearly, there is a need for a deep understanding of the fundamental mechanisms g- erning the process by which device, substrate, and supply noise turn into jitter and phase noise. Existing models generally offer only qualitative insights, however, and it has not always been clear why they are not quantitatively correct.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 224 pp. Englisch.

Buch. Condizione: Neu. Neuware -It is difficult to think of an example of an advancement in the biological sciences that has had an impact on society similar to that of the new genetics. Recent developments in biotechnology have occasioned much discussion among academics, professionals, and lay people alike. In particular, many questions and concerns have arisen over the acquisi tion, access, and control of genetic information. There are several reasons why the new genetics has commanded such widespread attention, and why it is now the subject of con siderable debate. Special reference is given in this volume to the implications of genetic information for five different subject areas: eugenics, the insurance industry, the commer cialisation of genetic testing, strategies for raising public awareness, and the value of theo retical ethical and sociological frameworks in the debate. This diverse collection of papers attempts to address and critically discuss issues surrounding the control of, and access to, genetic information from ethical, medical, legal, and theoretical points of view. The first and shortest section of the book attempts to address concerns over the eugenic potential of new biotechnologies. It also provides a historical context for the de bate, for controversy over the subject of eugenics predates the current debate over genetic information by a considerable length of time. Indeed, by the time the first patent was is sued for Chakrabarty's strain of oil eating bacteria in the early 1970s, the term eugenics had already acquired strong pejorative connotations.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 352 pp. Englisch.

Buch. Condizione: Neu. Neuware -Design of Low-Voltage Low-Power CMOS Delta-Sigma A/D Converters investigates the feasibility of designing Delta-Sigma Analog to Digital Converters for very low supply voltage (lower than 1.5V) and low power operation in standard CMOS processes. The chosen technique of implementation is the Switched Opamp Technique which provides Switched Capacitor operation at low supply voltage without the need to apply voltage multipliers or low VtMOST devices.A method of implementing the classic single loop and cascaded Delta-Sigma modulator topologies with half delay integrators is presented. Those topologies are studied in order to find the parameters that maximise the performance in terms of peak SNR. Based on a linear model, the performance degradations of higher order single loop and cascaded modulators, compared to a hypothetical ideal modulator, are quantified.An overview of low voltage Switched Capacitor design techniques, such as the use of voltage multipliers, low VtMOST devices and the Switched Opamp Technique, is given. An in-depth discussion of the present status of the Switched Opamp Technique covers the single-ended Original Switched Opamp Technique, the Modified Switched Opamp Technique, which allows lower supply voltage operation, and differential implementation including common mode control techniques.The restrictions imposed on the analog circuits by low supply voltage operation are investigated. Several low voltage circuit building blocks, some of which are new, are discussed. A new low voltage class AB OTA, especially suited for differential Switched Opamp applications, together with a common mode feedback amplifier and a comparator are presented and analyzed.As part of a systematic top-down design approach, the non-ideal charge transfer of the Switched Opamp integrator cell is modeled, based upon several models of the main opamp non-ideal characteristics. Behavioral simulations carried out with these models yield the required opamp specifications that ensure that the intended performance is met in an implementation.A power consumption analysis is performed. The influence of all design parameters, especially the low power supply voltage, is highlighted. Design guidelines towards low power operation are distilled.Two implementations are presented together with measurement results. The first one is a single-ended implementation of a Delta-Sigma ADC operating with 1.5V supply voltage and consuming 100 &mgr;W for a 74 dB dynamic range in a 3.4 kHz bandwidth. The second implementation is differential and operates with 900 mV. It achieves 77 dB dynamic range in 16 kHz bandwidth and consumes 40 &mgr;W.Design of Low-Voltage Low-Power CMOS Delta-Sigma A/D Converters is essential reading for analog design engineers and researchers.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 192 pp. Englisch.
